Opis:: The problem of estimation of finite population mean for current occasion in the context of cluster sampling on two successive occasions when there is non-response on both the occasions. Estimators for the current occasion are derived as the particular case when there is non-response on first occasion and second occasion only. A comparison between variances of the estimates is studied. An empirical study is made to study the performance of the proposed strategy.

Opis:: This paper considers a chain ratio-cum-dual to ratio type estimator for estimating population mean of the study variate using two auxiliary variates under double (two-phase) sampling procedure, when the information on another additional auxiliary variate is available along with the main auxiliary variate. The asymptotically optimum estimators (AOEs) in the class are identified in two different cases with their bias and variances. The optimum values of the first phase and second phase sample sizes have been obtained for the fixed cost of survey. Theoretical and empirical studies have also been done to demonstrate the efficiency of the proposed estimator with respect to strategies which utilized the information on two auxiliary variates.
